Whether it’s private planes, private trains, or gold-plated limousines, the mega-rich have always flaunted their wealth by buying luxury vehicles. Even when the only vehicles to buy were boats, chariots, and horse-drawn carriages.

The Bible says it’s harder for a camel to pass through the eye of a needle than for a rich man to get into heaven, but that didn’t stop these high rollers from trying. Meet the ancients who bankrolled the construction of massive churches and temples in an attempt to buy their way past the pearly gates.

The average American couple will drop five figures on their wedding. That wouldn’t even begin to cover the tab that these big spending couples racked up while throwing history’s most baller nuptial celebrations.
